i recomend you go to an auto tranny. it will aleviate alot of your gearing issues. the tourq converter at max slip has a 2 to 1 redution. it will get you that little bit more without having to regear everything and sacrifice top end. the only draw back of low speed auto is heat. the tourq converter while slipping generates ALOT of heat compaired to a manual. luckily an extra tranny cooler and fan are ususaly quite sufficiant.
